and i have to track while adding the items into the list.
How can I find out wheher the items are adding to the list or not?
any listener i have to add to the list. what listener and how can i use it?
I can find the items are added or not?
but i want to find the status after the addition started and before the addition completed

Any body help me?.

See java API specification
http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/JList.html
and
http://java.sun.com/docs/books/tutorial/uiswing/components/list.html

// Create a JList that displays the strings in data[]
 
 String[] data = {"one", "two", "three", "four"};
 JList dataList = new JList(data);
 
 // The value of the JList model property is an object that provides
 // a read-only view of the data.  It was constructed automatically.
 
 for(int i = 0; i < dataList.getModel().getSize(); i++) {
     System.out.println(dataList.getModel().getElementAt(i));
     // you could compare your element with the elements
     // which are on the JList here
 }
 

for example:

 final JList list = new JList(dataModel);
 MouseListener mouseListener = new MouseAdapter() {
     public void mouseClicked(MouseEvent e) {
         if (e.getClickCount() == 2) {
             int index = list.locationToIndex(e.getPoint());
             System.out.println("Double clicked on Item " + index);
          }
     }
 };
 list.addMouseListener(mouseListener);

 

 

Hello ,
we can find the item added or not by the method of size() of the list.

But I want to know status of the list

before the addition -- if size of the list is zero

after the addition -- if size of the list >0

during the addition --- how can i find it?

any body; help me please
